Coil packaging



The wire I I may be wound in any desired fashion such as criss-cross,level layer wound, honeycomb," etc., the particular winding'process notbeing a part of the present invention.

After the coil of wire is wound to its desired size, a first layer 29 ofdouble coated tape (that is,

tape which is provided with adhesive, so as to be tacky, on bothsurfaces) is wound about the entire cylindrical surface of the coil ofwire. The tackiness of the surface of the tape facing the outer layer ofwire of the coil, is of such a degree of adhesiveness as to retain orhold the outer layer of wire in position, but at the same time permitthe said outer layer of wire to be drawn off from the layer of tape whendesired during the payout operation. The tabs or fingers 2| of one ofthe end members [5 are then bent inwardly over said first tape layer 29to forma second layer 30. At the time of the positioning of the tabs 2|as set forth, in forming layer 30, one of said tabs is first threadedthrough a D- shaped metalring 3| for the purposes hereinafter comprisingtwo end members at least one of said setforth. If desired, several suchrings 3| may be positioned at various points about the periphery of thepackage. T a

A third layer 33'of double coated tape is then wound over said secondlayer 30 (of tabs 2 l) and the exposedportions of the first tape layer29. The next step in the fabrication of a package is to fold or bend thetabs 2| of the other end member l5 to form a fourth layer 34 over .thethird layer 33 (of tape). There is then wound a fifth layer 35, also ofdouble coated tape, over the fourth layer 34 and the exposed portions ofthe third layer 33.

While in Figurel of the drawing the tabs or fingers 2| ofone of the endmembers l5 are shown as'slightly spaced from the tabs of the other endmember, for purposes of clarity, it has been found that in the actualassembly of the package, the best results are secured when the tabsare'of such width-and are so oriented that the tabs of the two endmembers interdigitate with each other though separated by the third tapelayer 33. Thus it is seen that the two sets of tabs 2|, sointerdigitated, form a sheath of canvas (or other like strong flexiblematerial) encircling the lateral surface of the coil of wire. Part ofsaid canvas sheath is between the first and third layers 29, 33. and thebalance of said canvas sheath is between said third and fifth layers 33,35.

It is to be understood that I do not limit myself to the shape andnumber of tabs as shown in the drawing, as it may be desired to have thetabs 2| of each end member l5 so close to each other that said tabs forma complete rather than a partial covering when folded over the lateralsurface of the coil. v V 1 The package is then completed by applying asixth layer 31 of single coated tape (which is tape that is tacky onlyon the inwardly facing surface) completely about the fifth layer 35. Itis obvious, that in applying the tape-of the aforementioned layers, saidtape willby-pass the D-shaped ring 3| or rings. The rings serve as ameans for supporting the package when it is desired, as during thepayout operation.

While there has been described in the. specific embodiment a series of.sequential steps in the assembly of the package, it is obvious thatvariations in the assembly can be made. For example, the tab layers canfirst be applied .to the-outer lateral surface of the coils and then asingle or plurality of tape layers can be wound or other members havinga central opening, each of said membersincluding abody portion having anoutside diameter substantially equal to that of said coil and having aplurality of radially disposed tabs about the circumference of said bodyportion, and first, second, third, fourth, fifth and sixth layersdisposed successively about the outer lateral surface of said coil, said:first layer being of tape and covering, the outer lateral suri face ofsaid coil, said second layer comprising the tabs of one of said endmembers and at least partially covering said first layer, said thirdlayer being of tape and covering said second layer and'any'exposedportions of said first layer, said fourth layer comprising the tabs ofthe other of said endmembers and at least partially cover.-

ing said third layer, said'fifth layer being of tape,

and covering said fourth layer and any exposed portions of said thirdlayer, and said sixth layer. being of tape andcovering said fifth layer.

2. A package of the type described in claiml which includes meansforsuspending said pack- 1 age, said means including a ring and one tabof each of said-end members, said two tabs extendameter of said coil andhaving a plurality of radially disposed tabs about the circumference of1 said body portion, said tabs extending over the outer lateral surfaceor said coil, and. a side member which covers the lateral surface ofsaid coil and grips said tabs.

5. A package, for a coil of strand material, comprising two end members,each of said end members including a circular body portion having anoutside diameter substantially equal to the diameter of said coil andhaving a plurality of radially disposed tabs about the circumference ofsaid body portion, and a lateral member, said lateral member includingav plurality of layers about the lateral surface of said coil, saidlayers includingat least onelayer comprising a plu-' rality of turns oftape and said layers gripping saidtabs.

6. The method of. forming a packaged, hollow center coil of strandmaterial, comprising the steps of winding said strand material upon amandrel between two end members to form a coil of said material, each ofsaid end members-comprising a substantially, circular body having-apayout openingtherein and a plurality of radially disposed tabsextendingfrom the circumference thereof, wrapping a first layer of. tape.

over the outer lateral surface of said coil, bending the tabs of one ofsaid end members over said first layer to form a second layer, wrappinga third layer of tape over said first and second layers, bending thetabs of the other of said end members over said third layer to form afourth layer, wrapping a fifth layer of tape over said third and fourthlayers and wrapping a sixth layer of tape over said fifth layer.

7. The method of forming a packaged coil of strand material, comprisingthe steps of winding said strand material on a mandrel between two endmembers to form a coil of said material, each of said end memberscomprising a substantially circular body and a plurality of radiallydisposed tabs extending from the circumference thereof, bending saidtabs over the outer lateral surface of said coil and applying at leastone tape layer over said tabs.

8. The method of forming a packaged coil of 2 strand material comprisingthe steps of winding said material upon a mandrel between two endmembers to form a coil of said material, each of said end memberscomprising a substantially circular body of a diameter substantiallyequal to that of said coil and an extending portion, wrapping a firstlayer of tape over the lateral surface of said coil, bending saidextended portion of one of said end members over said first layer toform a second layer, wrapping a third layer over said first and secondlayers, bending the other of said etxended portions over said thirdlayer to form a fourth layer and applying at least one additional layerover said fourth layer.
